Technical Context

The R7FA6M4AE3CBQ#BC0 implements Armv8-M architecture with TrustZone security partitioning, enabling secure and non-secure execution environments. Its memory subsystem includes dual-bank flash for background programming and SWAP operations, plus 256 KB SRAM with configurable ECC or parity protection.

Connectivity is centered on a full-featured peripheral set: two CAN 2.0B controllers requiring external transceivers, an IEEE 802.3-compliant Ethernet MAC linked to EDMAC for zero-CPU packet handling, and QSPI/OSPI interfaces supporting external OctaFlash and serial NOR devices - all accessible via dedicated bus areas (EQBIU/EOBIU).

FAQ

What is the maximum operating frequency of the R7FA6M4AE3CBQ#BC0?

The R7FA6M4AE3CBQ#BC0 operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This frequency is achieved with the on-chip PLL driven by the main clock oscillator (8–24 MHz crystal) or high-speed on-chip oscillator (HOCO). The core maintains full performance across its rated temperature range of -40°C to +105°C.

Does the R7FA6M4AE3CBQ#BC0 include hardware cryptographic acceleration?

Yes, the R7FA6M4AE3CBQ#BC0 integrates the Secure Crypto Engine 9 (SCE9), which provides hardware acceleration for AES-128/256, RSA-2048/4096, ECC, SHA224/256, and GHASH. It also includes a 128-bit unique ID and tamper detection circuitry - all coordinated with Arm TrustZone to enforce secure key storage and cryptographic operation isolation.

What package type and pin count does the R7FA6M4AE3CBQ#BC0 use?

The R7FA6M4AE3CBQ#BC0 uses a 64-pin Fine-Pitch Ball Grid Array (FBGA) package, designated PLBG0064JC-A, measuring 6 mm × 6 mm with 0.65 mm ball pitch. It provides 45 general-purpose I/O pins, 9 of which are 5-V tolerant, and supports N-ch open-drain output configuration on all I/Os.

Can the R7FA6M4AE3CBQ#BC0 support Ethernet communication without an external PHY?

No, the R7FA6M4AE3CBQ#BC0 includes only an Ethernet MAC controller compliant with IEEE 802.3, not a full PHY. It requires an external RMII-compliant PHY (e.g., LAN8720A or DP83848) connected via the ETH_MDIO, ETH_MDC, and RMII signal pins. The MCU handles MAC-layer framing and DMA transfers via EDMAC, offloading the CPU.

How many CAN interfaces does the R7FA6M4AE3CBQ#BC0 support, and what standards do they comply with?

The R7FA6M4AE3CBQ#BC0 supports two independent Controller Area Network (CAN) modules, each compliant with ISO 11898-1 (CAN 2.0A and CAN 2.0B). Each module supports up to 32 mailboxes configurable for transmission or reception in normal or FIFO mode, and both standard (11-bit) and extended (29-bit) identifier formats - requiring external CAN transceivers for physical layer interfacing.
